If she has a facebook profile, it's either completely private (so it does not even get listed if you search for it) or she has stuck it under a (maybe only slightly) different name. There are 2 Kim Sears, but one has no friends, the other only one in the states, so it's unlikely it's her in both cases...

Plus, since the girl has enough brains to go to Uni, I'd expect her to completely lock down her account via privacy settings to avoid a reoccurrence of the 'bebo troubles'...
